engine 'hesitating', on open road.Cutting out at low revs.

[tonytype25]

My 1991 2.1 injected petrol is losing power for a second or less at regular intervals while in 4th or 5th gear while on long trips on the open road.
I also find that its cutting out while waiting at traffic lights and at junctions. Any ideas as to the cause?
